Introduction
The equipment of power electronics application is comprised of general use inverters, numeric control (NC) machine tools, and industrial robots.
Recently, the requirements of lower noise, higher efficiency, advanced functions, lower price, and downsizing for these items have been growing.
The power devices used as the equipment of power electronics applications are progressing toward lower loss and higher frequency, and the IGBT (insulated gate bipolar
transistor) rather than the bipolar
transistor is gaining popularity.
On the other hand, together with lowered loss for the IGBT, intelligence is achi...
